No, not the application.link API. A web link. Or two.
Some of you may have noticed a new name on the HD DVD Forums of late: Amy Dullard. She also has a great blog that focuses on getting people up-and-running with HDi. Check it out at http://blogs.msdn.com/amyd.
Another person you might recognise from the Forums, Andy Pennell, also has a blog at http://blogs.msdn.com/andypennell/.
And finally, the Microsoft "industry" site for HD DVD is http://www.thisishddvd.com. There's not much there now, but it should get better.
OK, so three links. Four if you count the forums. But who didn't know that already?
